Well, one possibility is that Naruto is banished from his own world for some unjust reason. In Karakura, he could discover new powers related to the spiritual energy there. He might start by being confused but then adapt and use his ninja skills in unique ways to deal with the Hollows and other threats in Karakura. Maybe he forms new alliances with the local characters like Ichigo and his friends.
A powerful Hollow could be the main antagonist. This Hollow could sense Naruto's unique energy and see him as a threat to its plans of taking over Karakura. It might constantly target Naruto and his new friends, trying to eliminate them one by one.
One possible plot could be Naruto being somehow transported to Karakura Town. He might initially be confused by the different setting compared to the Hidden Leaf Village. He could encounter the local characters from Bleach, which is set in Karakura Town. Maybe he would team up with Ichigo and his friends to fight a common enemy that threatens both the ninja world and Karakura Town.
Definitely Naruto and Ichigo. Ichigo has his own set of powers as a Soul Reaper and Naruto has his ninja abilities. Their different personalities and ways of fighting would make for an interesting dynamic. Ichigo is more brooding and Naruto is very energetic, so seeing them interact and work together would be cool.
Naruto might also initially feel a sense of abandonment. However, his kind - hearted nature could lead him to try and see the good in the situation. He could start to explore the world outside, learning about different cultures and ninja techniques. He may use this experience to become more empathetic towards others who have also faced hardships, and in the long run, this banishment could be a turning point in his life to become an even greater ninja.
At first, Naruto is probably shocked and confused. He might not understand why the village would take such a harsh step just for hurting Sasuke. He may feel betrayed, especially if he thought he had friends and allies in the village.
A possible plot for this type of fanfiction could involve the banished ninja having a secret mission that the village doesn't want to be associated with. So, they banish the ninja to make it seem like they have no part in it. The ninja then has to complete the mission while also dealing with the stigma of being banished.
Well, in a fanfiction like this, it could explore Naruto's sage mode abilities in a new context while he's with Yugito who has also been banished. Maybe they form an alliance to fight against the forces that banished them. They could discover new powers together and change the shinobi world's view of them.
In a 'Naruto and Anko Banished' fanfiction, the story could start with a false accusation against them. This would lead to their banishment. Once exiled, they could encounter new enemies and allies. For example, they might meet a group of outcasts who teach them unique jutsu. This would add new elements to their fighting styles and also change their perspective on the ninja world.
